This PR introduces two new things: a pass of the analyzer that
recognises exports from CJS modules (in the form of `exports.foo`, see
`analyze_cjs_exports`) and then a CodeGen that reads `export_usage_info`
to remove CJS exports that are not used.
This PR does not add anything additionally to `export_usage_info`, so
this means that we only trim from modules that are imported with `import
{ foo } from "bar"`. The CodeGen depends on the output of
`analyze_cjs_exports` for the locations of exports, whether it is safe
to drop exports (its pretty conservative), and also whether `__esModule`
is present.
